Iodizing agent and process for preparation thereof
a technology of iodizing agent and process, applied in the field of new iodizing agent, can solve the problems of iodine loss, significant iodine loss, and rapid loss of iodine in most unrefined salt samples, and achieve the effects of reducing the cost of salt purification, preventing chemical degradation, and promoting the use of sal

[0049] 6 gm of hydrotalcite having molar ratio of MgO:Al2O3 equal to 6.0, XRD pattern having intensity peaks (Ao) 7.77, 3.87, 2.57, 1.53, 1.50, 1.42, and sharp IR absorption peak of interlayer carbonate ions at 1370 cm−1, was powdered to pass through 60 BSS mesh and calcined in a furnace at 500° C. for one hour. The calcined hydrotalcite was cooled to 65° C. This was added to 100 ml of 0.01M potassium iodate solution prepared in distilled water, which is heated to 70° C. prior to addition. The reacting mass was stirred for five minutes maintaining the said temperature and left to stand for one hour with intermittent stirring for one minute at an interval of 30 minute. The resultant slurry was filtered. The solid separated was washed with distilled water till the wash filtrate does not show any silver iodate precipitate with silver nitrate. The solids were dried at 110° C. The dry material was analyzed for its iodine content using classical method of iodometry employing sodium thiosu...

[0050] 6 gm of hydrotalcite having molar ratio of MgO:Al2O3 equal to 5.5, XRD pattern having intensity peaks (Ao) 7.60, 3.82, 2.57, 1.53, 1.50, 1.42, and sharp IR absorption peak of interlayer carbonate ions at 1365 cm−1, was powdered to pass through 60 BSS mesh and calcined in a furnace at 450° C. for one hour. The calcined hydrotalcite was cooled to 80° C. This was added to 50 ml of 0.005M potassium iodate solution prepared in distilled water which is heated to 80° C. prior to addition. The reacting mass was stirred for five minutes maintaining the said temperature and left to stand for one hour with intermittent stirring for one minute at an interval of 30 minute. The resultant slurry was filtered. The solid separated was washed with distilled water till the wash filtrate does not show any silver iodate precipitate with silver nitrate. The solids were dried at 110°C. The dry material was analyzed for its iodine content using classical method of iodometry employing sodium thiosulp...

[0051] 6 gm of hydrotalcite having molar ratio of MgO:Al2O3 equal to 6.0, XRD pattern having intensity peaks (Ao) 7.77, 3.87, 2.57, 1.53, 1.50, 1.42, and sharp IR absorption peak of interlayer carbonate ions at 1370 cm−1, was powdered to pass through 60 BSS mesh and calcined in a furnace at 525° C. for one hour. The calcined hydrotalcite was cooled to 60° C. This was added to 50 ml of 0.01M potassium iodate solution prepared in distilled water which is heated to 60° C. prior to addition. The reacting mass was stirred for five minutes maintaining the said temperature and left to stand for one hour with intermittent stirring for one minute at an interval of 30 minute. The resultant slurry was filtered. The solid separated was washed with 200 ml distilled water till the wash filtrate does not show any silver iodate precipitate with silver nitrate. The solids were dried at 110° C. The dry material was analyzed for its iodine content using classical method of iodometry employing sodium t...
